The results show that the influences of various backings on the acoustic characteristics of anechoic coating are obviously different.
结果表明，不同背衬对吸声覆盖层吸声性能的影响具有明显不同的特性。
3
The lining and the exterior fabric are actually produced as one integral layer, eliminating the need for additional adhesives or backings that can limit airflow.
